This invention rebates to improvcmcius in still will suffice. Thegenerator 1 comprises \vucr stills and more lullllttllllll) to an irru.hollow body which, in the present illusproved construction of condenserfor such a -truted embodiment of the invention is of still undmcuns forsupplying cooling water rectangular form and comprises-surroundingthereto and one of the objects of the prrswalls 5 and other walls 6which are spaced out invention is to provide a condenser inwardly fromthe walls 5 and connected constructed as to insure of rapid-21ndecotherewith by a bottom 7, forming a preheatuoniicul condensation ofthe water vapors ing chamber 8 into which water is introwith a minimumwaste of water for cooling duced by a supply pipe 9 provided at its toppurposes and which condenser. will present wvith a funnel 10, thepurpose of which will he presently explained. A bottom wall 11 isarranged within the bounds of the. walls (5 and defines, in conjunctionwith the upper portions of said walls 6, a enerator chamber indicated bythe numera 12, the walls 6 having openings 13, formed therein to providefor the passage. of preheated water from the ireheuting chamber 8 intothe gen eruting chumber 12, whereby a constant shallow level of water ismaintained upon the bottom ll and rapidly converted into steum, theapparatus being, of course, arranged with thcopen bottom of thegenerator above a sourccof heat as, for exumplc, a cooking range. Aplule 14-- is arranged within the generator to rest upon the upper-edgesof the wells 6 and is formed with perforations 15 u d 16 locatedrespectively .above and communicating with the preheating chamber 8 andgenerating chamber 12, so that the steam generated in these chambers andespecially in the chamber-12, may pass upwardly through the open top ofthe generator.

The receiver 2 comprises a hollow rectangulcir body 17 provided in itsupper portion with 1:. receiving pun 18 having a number of short nipplesor spouts 19 extending upwardly Ewni its surface and establishingcomnmnicelion between the spaces above and below the pun .A Will-("1'outlet pipe 20 leads from the lowermost portion of the pan, the punbeinginclined from all sides toward its mid-portiomand serves to carryoff the distilled water. 'lhc body of the receiver isrcumvubly,disgaoscd upon the top of the body oi the generator. and thecondenser 3 is, in turn, supported upon the top of the receiver.

The condenser 21 comprises a hollow rectangular body includingsurrounding walls indicated by the numeral 21, the body being disposedat its open lower end to rest upon the opcn upper end of the receiver 2,as clcurly shown in Figure 1 of the drawings. Arranged within the bodyof the condenser 3 above thenipen lower end thereof is a b lotlic vaporsto becondcnscd. usnaxinium pooling or condensing surface within a givenspace.

Another object of the invention is to so construct the condenser thatobnoxious volutile impurities in the water ill be carried off so as notto contmninatc the dis ilate,

Another object of the invention is to so coiwtruct the inc-ens providedfor supplying co. r water to the condenser that the wutcr wi 1 beinitially introduced into the condenser at a point where its coolingeffect will prove most effective and in such uuumcr that the exchange ofheat will tulrc place in u way to insure of complete condensation of thewater vapors or steam in the most e-fl'ectivc manner.

Another object of the invention is to provide, in connection withu'condenscr,-a novel construction of reservoir and means associatedtherewith for supplying cooling water to the cooling water chambers ofthe condenser.

The still embodying the invention conr ises, gcucrully speaking, agenerator which is indirzdcd in ueucrul by the numeral 1, a receiverindicated in gcncrul by the numcrul .u, .i condenser iudiculcd ingcncrzil by the numeral 3, and in cooling water reservoir indicated ingeneral by the numeral 4. 'l'hc grncrutor l and receiver 2 arcv of thocoir strucli n illustrated and described in urv ropcudinc applicationScriul Nu. (Jul-5!. lilcd December 4. ill-33, and, consequently. u briefdescription of thcsc riuupoucnt pulls ol' the 22, which is formed atintervals throughout means to be presently described, and it wi l itsarea with parallel longitudinal slots 23 into which are fitted andsecured, in a fluidtight manner, the open lower portions of condensationchambers indicated in general by the numeral 24. Each of these chambers.

comprises side walls 25, end walls 26, and a closed top 27, and thearrangement of the chambers is best illustrated in Figure 2 of thedrawings, It will be observed by reference to this figure and Figure lof the drawings, that thechambers are spaced 'so that coolin waterchambers 28 are provided between eac two adjacent ones of the chamhers24, and that similar cooling water chambers 29 are provided between theside walls of the endmost ones of the series of chambers 24 and thecorresponding side walls 21of the body of the condensen'the' end walls26 of the chambers 24 being likewise spaced from the other side walls ofthe body of the condenser to provide cooling water chambers 30. Wateristo be introduced into the "cooling water chambers b be evident at thispoint that steam rising through the nozzles 19 will enter thecondensation chambers .24 and be condensed upon comin in contact withthe cooled walls of the chambers 28, 29 and 30 the condensate drippingonto the surface of the pan 18 of the receiver 2 and flowing 'outthrough the pipe 20. The tops 27 of the-condensation chambers 24 arespaced below the open top of the body of the condenser3, and vent pipes31 are fitted at their lower ends into openings in the said tops. 27 ofthe condensatwo chambers and extend above the chamhers to a point spacedslightl below the up r edges of the walls 21 of t ie condenser bo y.These pipes, as best shown in Figure 4 of the drawings, are closed attheir upper ends, as indicated by the numeralli32, exce t that in theirsides, immediately below their upper extremities, they are formed with acircumferential series of openings indicated by the numeral 33, throughwhich any obnoxious volatile impurities in the water or, more secifically the 'watervapprs enerated in t e generator, may pass t .rougportion of condenser body, these gases findin exit by way of aseries ofopenings 34 which are formed i'n'th'e walls 21 of the body of'thecondenseri'n a plane above the plane occupied by the closed upper endsof the vent pipes 31, the said' openings '34 establishing communicationbetween upper ortion of theinterior of the condenser ody and theatmosphere.

Water is supplied to the condenser from the reservoir 4 which comprisesahollow rectangular body including side walls 35, end walls 36, a closedtop 37', and a bottom 38, the ieservoir being removably disposed theP1181? at'its lower side upon the upper ed es of the walls 21 of thebody of the con enser 3. The bottom 38 of the reservoir 4 is preferablyin the form of "a relatively thick metal late which, as best shown inFigure 3 of' t e drawings, is formed in its under side at suitableintervals, with threaded openings 39 which extend part way through theplate, the plate being further formed, centrally of each opening 39,with a smaller opening or vent 40 communicating with the opening 39 ando ening through the upper side of the said p ate. The arrangement of theopenings 39 and 40 is preferablysuch that one, two, or any other desirednumber of such openings 39 will be located directly above the open upperend of the cooling water chambers 28 and 29, as best illustrated inFigure 2, and a distributin pi is threaded at its upper end and tte intoeach 0 ning 39,'the upper extremity of the pipe a utting firmly againstthe upper wall of the respective opening and the connection of the pipeswith theplate 3S comprising the bottom of'the reservoir 4, being in thismanner firmly established. Itwill be observed by reference to Figure 3,that-the openings 40 are of considerably less diameter than the openings39 and the bores of the respective pipes 41, so that, byreason of thisconstruction, no sediment or 'particles of foreign matter can enter thepipes ll which would be of a size to clog the pipes.Anotheradvantage-resulting from this peculiar manner 0 connecting thepipes with the bottom plate 38 is that there is no possibility of theupper ends of the pipes 41 projecting above the surface of the plate sothat thesaid surface of the-plat'e is left entirely smooth,therebyproviding for an equal (llStllblltlOfl'Of water to all the pipes.and preventingthe accumulation of sediment or foreign matter.

A water supply pipe 42 is fitted at through one of the side Wal s 21 ofthe con n the top of the condenser 3 denser body and has its inner endturned 7.

downwardly, as at 44, and this pipe leads to any suitable-point ofdischarge as, for example, a kitchen sink, and manually adjustableout-0d or reljulating valves 45 and 46 are arranged in the pipes 42 and43 respectively, so that the supply of water to the reservoir 4 and thedischarge of water through the outlet pipe 43 may be proper- 1yregulated to maintain the proper water level within the condenser. Atthis point,

it will be evident that cooling water is continuously supplied to thecondenser and permitted to overflow from the same after it has servedits purpor'e and that the water is upplied to the cooling water chambersat their portions which are subjected to the highest degree oftemperature, the water initially supplied being. or course, at a lo\v ertemperature than the water overflowing from the condenser. "Therefore,the walls of the condensation chambers 24 are equably cooled tocorrespond to the temperature variations prevailing over ditl'erentportions of their areas.

As in my previously mentioned co-pcnding application, a second overflowpipe 47 is led from the side of the condenser body 8 with its lower endentering the mouth of the tunnel ltl,-and a cut-oil valve 49 isinterposed in this pipe and may be adjusted to permitof a regulated flowof Water through the said pipe 41' to the funnel 10 and from the tunnelthrough the pipe 9 to the preheating chamber 8. As the water in thecondenser is heated throug i the exchange of heat between it and thewalls of the condensation chambers. and rises to the overflow, thispartially heated water is delivered to the preheating chamber, therebyeffecting an economy in fuel.

In the wings, the apparatus is illustrated as of general rectangularform but it will be readily understood that it may be of cylindricalform and that the coin densation chambers and water cooling chambers mayhe made annular or cylindrical. as this general idea is embraced in myctr-pending a 'iplication Serial No. 678.45%), filed December 4, 19:33,and it is obvious that the water reservoir of the pres-.rnt applicationmight be employed in connection with the condenser of the said (apending application with the necessarymodification.
